MINNEAPOLIS, MN — Nationally recognized for a 30% reduction in energy use, the One Verizon Way building in Thousand Oaks, CA, was the first in the state to retrofit old-style chillers with the new McQuay MicroTech™ Control Panels and a chiller system control panel. These controls, along with other HVAC improvements, contributed to the building’s increased energy efficiency, earning it the Energy Star award from the US Department of Energy and the Environmental Protection Agency.

The retrofitted chillers run at multiple stages based on demand. Efficiency is increased by operating the system with the least amount of chillers on-line and at near-full capacity.

To further reduce energy costs, Verizon installed a McQuay WHR050 water-cooled dual compressor reciprocating chiller to cool the building’s computer data center. The system reduces energy costs by running at reduced loads. On nights and weekends, year round, the chiller handles eight chilled water fan coil systems, including the data center, while running at only 25% of full load.
